I use this stuff with excellent results... it puts a glossy finish on your wheels that last and doesn't come off.... It's a black trim restorer so it works excellent on that as well.....
I recently used this on my factory Dark Horse wheels and it looks fantastic. It basically put a glossy clear coat on the wheels. It's for plastic trim restoration but works great on wheels as well.
I think it sounds absolutely perfect but we'll see what everyone else has to say as we all have our opinions.... I bought the x-pipe but I'm not going to use it because I like the way it sounds too much to switch it....
I'm going to make a video so you can hear it......and I recently found out in drag mode with it pinned to the floor at around 60 mph shifting from 5 to 6 gear it chirps the wheels which I think is insanely fun 😁
Here's my only regret.....I had some nice crackles and pops with the stock resonator, but after switching to the H pipe that has all gone away ..... no more snap crackles and pops for me which has me pondering the x-pipe.....
Also I never use quiet mode, I mean I didn't buy a Mustang for it to be quiet you know..... With my setup I want to be able to use normal sport and track all with different variations of the exhaust tone....
I wasn't sure it what was inside so I did a search and from what I gathered it's just two straight pipes inside with no crossover with either an X or an H....
On BORLAs page they have a video that the owner put up about organ pipes and how different sizes and shapes that those pipes produce which is similar to the different size and shapes, and configurations that exhaust pipes produce....
